Did I fry my fans by wiring them backwards?

[AquariusPanta]

LOL!

 

[jpizzle4shizzle]

I know nothing of wiring or how to be an electrician but you would think people would know this Lol its actually the only thing I know

Whatever you do, do NOT cut the red wire.

 

[AquariusPanta]

Yeah, what this fella above said

 

[Jeeyah]

Finishing up my light and blew one of the fans. My old cell phone charger has - signs on the positive wire. Pissed.

On the drivers brown is hot, and blue is neutral right? Just making sure.

Yes, sir.

I've wired both CPU fans from Arctic and Intel backwards and always got them to operate after by making an adjustment. I did however fry one of my Intel fans when using the yellow wire (it was neither negative or positive).

OK... So I plugged in a series of 4 artic 11 fans and they all ran, i accidently switched the wires for no more than 4 seconds now None of them are working. Is there a way to recover them??? I don't want to know that I just fried $40 bucks worth of fans from such a stupid mistake.

See if any of them work individually... How much voltage was in the series? all 48v's? or 20v [4x5v]...

There was 4 fans at 12v a piece, totaling 48v, I was using a small wall charger that pushed 12v at 1250mA. I tried each one one at time and none of them are responding, I opened up a new one I had laying and it worked, then I accidentally switched the polarity again, (it's not labeled) now the new one isn't working either. The eff is up with these fickle azz fans, I've used dozens of fans before and switched wires, run them in parallel etc... Never had one die ever, espically like these.

How can you push 48v's with a 12v charger? That is impossible......although you said you got the same results from a single one which is weird and I was going to guess, probably a zener that blew...........

So to be clear you had 4 fans hooked in series thru a 12v charger?
Each fan would be receiving 3v's and most won't spin on with that amount of power...time to get out the multimeter if you have one....but certainly something isn't adding up, if you used a single fan on the 12v's as well....

Sorry I ran 3 on a 12v wall charger, so 4v each, it sounds like I fucked up the wall charger. Err imma look for a higher V charger and see what the results are.

fans need to be hooked to the PS in parallel, not in series.

160mA is what that fan is supposed to take, and you tried putting 1250mA through them? No current limiting resistor?

This is why people need a basic benchtop power supply, and a multimeter.
Watching people "tinker" without them is like watching someone commit seppuku with a rusty letter-opener

 

[The Dawg]

The yellow is NOT 5v...it is for the PWM signal. Which needs up to 5v...but is not meant to power the fan...that 5v is meant to interrupt the normal 12v coming in on the red wire and dim it...nothing else.


ONCE AGAIN...ALL YOU NEED IS BLACK AND RED WITH APLINE COOLERs. NOTHING ELSE.
I am very surprised to hear so many people flirting with that stupid yellow wire. Leave it alone.

You are absolutely right, which is why I just bought one, and I used 1.2A to drive 4 but made a noob mistake on the V side.

Do you have a multimeter....

Wire them up in parallel and see if it works....its all good

by putting1.2A through those fans, they might be damaged.

WELP...word to EVERYONE who is thinking of using the ARTIC 11 Fans...DO NOT MIX THE WIRES. POS to POS, NEG to NEG, if you swtich them it will FRY your fan, i just lost 5 fans tonight, i'm simply going to order replacement fans for the ones i have lost and keep it pushing. i know they are fried because i found another 9v wall charger, tried it with a new fan (the 3 i have left) and it worked just fine, i tried my other wall charges from before that were 12v and they all worked just fine. i tried it on one of the 5 ones i thought broken, aaaaand not a single one worked!

I re-looked over all my wiring and i indeed ran them in parallel and wired the properly i chose 1250mA to give them a little wiggle room given they run at 250mA a piece. When i switched the polarity...it fried every single fan in that line, which was all 4.

and no i don't have a multimeter, but i am going to pick one up tomm morning. i thought i had one in the garage, i was wrong lol.

It happens, at least fans are cheap.
